    [PATCH] Change MD Superblock IO to go straight to submit_bio · bd415ca2
    Neil Brown authored
    The current code hits the page cache for the block device
    which requires memory allocation which can sometimes cause
    a deadlock (if it blocks the raid5d thread).
    
    This code takes the page that holds the superblock, and
    passes it to submit_bh in a suitable bio wrapper.
